I disagree with the review. The book doesn't contain a complete and perfect path to personal wealth for anyone. But what book could ever accomplish that?
Disclaimer: I read it several years ago. But the takeaways of the book that stayed with me to this date are:
* Don't get emotionally attached to the concepts of money and debt. Money is not worth anything by itself and debt is not bad by itself. They are simply tools that you use and you can use them wisely or foolishly.
* Try to invest your money and time in a way that creates recurring income. I.e. a house is a very bad investment because it creates recurring costs rather than income. Of course you need somewhere to live but don't get emotionally attached to the idea that happiness equals living in a fancy house or driving a fancy car.
* Debt is nothing more and nothing less than a tool for creating recurring income as long as the costs of the debt are lower than the income it creates. Discounting for risk etc.
* The way we teach our kids "the value of money" is creating exactly the emotional ties above that will lead them to making bad decisions about their personal finances, and ties their happiness to how much money they have in the bank.
I don't know if these points are what the book says, simply because I don't know how much of it is my own interpretations. But reading this book allowed me to come to a number of conclusions that have been very helpful ever since. I can think more clearly about what money, income, debt and costs really are.
